Microsoft Patch Tuesday, March 2022 Edition

Microsoft on Tuesday released software updates to plug at least 70 security holes in its Windows operating systems and related software. For the second month running, there are no scary zero-day threats looming for Windows users (that we know of), and relatively few "critical" fixes. And yet we know from experience that attackers are already trying to work out how to turn these patches into a roadmap for exploiting the flaws they fix. Here's a look at the security weaknesses Microsoft says are most likely to be targeted first.

How the tech community has rallied to Ukraine’s cyber-defence | Joyce Hakmeh and Esther Naylor

From an army of volunteers to EU and Nato teams, the variety of online actors working for the cause is unprecedented

As the conflict in Ukraine escalates, expert cyber-watchers have been speculating about the kind of cyber-attacks that Russia might conduct. Will the Kremlin turn off Ukraine’s power grid, dismantle Ukraine’s transport system, cut off the water supply or target the health system? Or would cybercriminals operating from Russia, who could act as proxies for the Russian regime, conduct these activities?

Over the past decade, Ukraine has experienced many major cyber-attacks, most of which have been attributed to Russia. From election interference in 2014, which compromised the central electoral system and jeopardised the integrity of the democratic process; to a hack and blackout attack in a first-of-its-kind fully remote cyber-attack on a power grid in 2015, resulting in countrywide power outages; to one of the costliest malicious software attacks, NotPetya, in 2017, which significantly disrupted access to banking and government services in Ukraine and, subsequently, spilled over to France, Germany, Italy, Poland, Russia, the UK, the US and Australia.
